Recommendations for clothing

Sorry if this has been asked before, but I'm on a budget and looking to find non see through and non sweat showing workout capris. I'm treadmill running twice a week, group weights workout twice a week, one HIIT session and one indoor circuit. Lots of squats!!! Looking to buy a couple of pairs that are suitable for all workouts. Also, can anyone tell me where I can find a good selection of non racerback tank tops? I'm not overkeen on showing off my bra straps :-) I'm in the UK. Thanks
